You are raising a question of civil (contract) law, so there are no fixed legal tomes of remedies for anything. You can sue on the warranty contract any time you like, but your chances of prevailing will depend on a variety of circumstances, not the least of which is the wording of the contract itself. Have you looked at what it says about resolving disputes? It is not unusual to require binding arbitration instead of a lawsuit. And what sort of remedy are you looking for? A replacement RV? Money back? A different repair shop to work the problem?
I think your chances of a successful suit are slim as long as qualified people are actively engaged in trying to find a fix, but my opinion is irrelevant. You should consult an attorney to see what remedies might be attempted. You may have other rights/remedies available under Florida consumer law.
